Chronic Upper Respiratory Disease in Cats: Welfare Management

Chronic upper respiratory disease in cats causes persistent discomfort and requires long-term management to maintain quality of life.

Key Facts

Often follows herpesvirus infection in kittenhood — virus persists lifelong
Signs include nasal discharge, sneezing, eye discharge and nasal congestion
Stress reliably triggers flare-ups due to viral reactivation
Lysine supplementation is no longer recommended — evidence of benefit is poor
Good hygiene, stress reduction and antiviral treatment during flares are mainstays

Welfare Considerations

Cats with chronic herpesvirus-related upper respiratory disease experience recurring episodes of discomfort — blocked nasal passages reduce smell, impairing appetite and quality of life. In multi-cat households, stress is a constant challenge for affected cats. Minimising stress through environmental enrichment, feliway diffusers and thoughtful household management reduces flare frequency. Severe chronic cases with nasal polyps or turbinate destruction require surgical intervention.

What You Can Do

Identify and reduce stress triggers for cats with chronic respiratory disease
Use environmental enrichment and pheromone diffusers to reduce flare frequency
Seek veterinary assessment for any cat with persistent nasal discharge
Discuss antiviral treatment (famciclovir) with your vet for severe herpesvirus cases
Ensure adequate nutrition during respiratory flares — warming food enhances smell
